A rare vintage 1991 Rolex Submariner reference 1680 retailed and signed by Tiffany and Co., featuring a black dial with tritium hour markers and hands, caliber 1570 automatic movement, bidirectional rotating bezel, and original stainless steel Oyster bracelet with short links - in excellent condition with original Rolex warranty card and Tiffany and Co. box.

The Rolex Submariner reference 1680 is one of the most historically significant and collectible references in the entire Rolex catalog — introduced in 1966 as the first Submariner to feature a date complication, it established the blueprint for every subsequent date-equipped Submariner through to the present day, and its production run through the late 1980s and early 1990s captured the watch at the peak of its mechanical and visual maturity. What elevates this particular example to the highest tier of Submariner collecting is the Tiffany and Co. co-signed dial — a prestigious retail partnership between Rolex and America's most iconic luxury jeweler that resulted in a limited number of Rolex watches being signed by both brands on the dial, a practice that ceased in the early 1990s and which has since made Tiffany-signed Rolex references among the most aggressively pursued and rapidly appreciating references in the vintage watch market. Recent auction results for Tiffany-signed Rolex references have consistently achieved multiples above equivalent unsigned examples, with single-owner provenance and original box and papers adding substantial further premium. This 1991 example in excellent condition, with its original Rolex warranty card and Tiffany and Co. box intact, represents one of the most complete and investment-grade Tiffany Submariner packages available outside of major auction.

The 40mm stainless steel case presents the classic Submariner profile with the characteristic crown guards flanking the winding crown and the broad, angular lugs that define the reference 1680's immediately recognizable silhouette. The matte black dial carries the dual signature of "Rolex Oyster Perpetual Date" above and "Tiffany and Co. Submariner 1000ft/300m" below center — a layout that announces the co-branding clearly without disrupting the clean, functional legibility that makes the Submariner dial one of the most perfectly designed instrument dials in watchmaking history. Tritium luminous material fills the rectangular hour markers, dot minute indicators, and both hands, producing the characteristic warm patina glow at the dial's surface that vintage Submariner collectors prize as a marker of authentic, unrestored examples. The bidirectional rotating elapsed time bezel features a matte black aluminum insert with minute graduations and the characteristic gold-tone pip at the 12 o'clock position, completing the full sporting specification of this legendary reference.
